Just months before the tragedy which killed four guests, Dreamworld looked into simplifying the emergency stop procedure on the Thunder River Rapids Ride.
The four-step procedure which was to be utilised in an emergency situation on the 30-year-old ride has been a subject of discussion during an inquest into 2016 tragedy.
On Friday, the Southport Coroners Court heard attractions manager Andrew Fyfe asked a staff member to seek advice on whether the procedure could be simplified into a one-button process.
Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozi Araghi all died when the ride malfunctioned in October 2016.
Attractions supervisor Jason Johns was undertaking a review of the operations procedure of the ride in May 2016 when he emailed engineers.
"What is the possibility of having the below steps changed from individual steps into one step?," Mr Johns asked.
He told the inquest he'd made the request at the behest of his manager Mr Fyfe and not due to any concerns being raised by ride operators.
He added he had no further correspondence on that issue apart from an acknowledgement from engineers that it would be looked into.
There are concerns witnesses may have to be recalled to the inquest after lawyers representing Dreamworld's owners Ardent Leisure provided over 1000 new documents as evidence to the inquest on Monday.
Barrister Matthew Hickey, representing Ms Low's family, said the documents contained information relevant to both future and past witnesses.
Mr Hickey said despite being aware of time constraints for the inquest, there was a need for "families of those whose lives have been robbed" to know the full story.
The inquest is set to resume on Monday with external contractors and parts suppliers to provide evidence.
